Abstract

METODO PARA LA PRODUCCION DE MEMBRANA DE FIBRA HUECA, MEDIANTE LOS PASOS DE LA DESCARGA DE UN BARNIZ EN ESPIRAL A TRAVES DE UNA BOQUILLA ESPIRAL ANULAR Y, AL MISMO TIEMPO, LA INTRODUCCION DE UN LIQUIDO ANTICOAGUALNTE PARA EL BARNIZ EN LA CAVIDAD CENTRAL DE UNA FIBRA HUECA DEL BARNIZ QUE SE ESTA DESCARGANDO, Y LA POSTERIOR INTRODUCCION DE LA FIBRA DE DESCARGA DEL BARNIZ EN UN LIQUIDO COAGULANTE DONDE SE SOLIDIFICA LA FIBRA DESCARGADA EN UNA MEMBRANA DE FIBRA HUECA. ESTE METODO SE CARACTERIZA POR LA INCORPORACION DE UN AGENTE MODIFICADOR DE LA SUPERFICIE EN DICHO LIQUIDO ANTICOAGULANTE, MODIFICANDO EL COMPORTAMIENTO DE LA SUPERFICIE INTERNA DE LA MEMBRANA DE FIBRA HUECA PRODUCIDA.METHOD FOR THE PRODUCTION OF MEMBRANE OF FIBER HUECA, THROUGH THE STEPS OF UNLOADING A SPIRAL VARNISH THROUGH AN ANNULAR SPIRAL NOZZLE AND, AT THE SAME TIME, THE INTRODUCTION OF AN ANTICOAGUAL LIQUID FOR THE VARNISH IN THE CENTRAL CAVIBLE OF A FIBER HOLLOW FROM THE VARNISH THAT IS DOWNLOADING, AND THE FOLLOWING INTRODUCTION OF THE VARNISH DOWNLOAD FIBER IN A COAGULATING LIQUID WHERE THE DOWNLOADED FIBER IS SOLIDIFIED IN A HUECA FIBER MEMBRANE. THIS METHOD IS CHARACTERIZED BY THE INCORPORATION OF A SURFACE MODIFYING AGENT IN SUCH ANTICOAGULATING LIQUID, MODIFYING THE BEHAVIOR OF THE INTERNAL SURFACE OF THE PRODUCED FIBER MEMBRANE.
